Very high value homes are often discounted more but the truth is the owners of them want money spent on high profile but ineffective marketing mediums like Dream Homes magazine. Its an ego thing to see your home in it. They also take longer to sell, sometimes years and quite often dont sell. Many agents operating in the high end markets do 2 to 4 transactions a year after spending months and months with clients not getting paid anything. Its the nature of that market.

As for remote visual tours being used to screen many homes the answer is yes. Its been that way for over a decade and none of that is new. Personally I think great quality stills are more effective then video and most tours are just slide shows of stills anyway.

So much perceived differentiation out there is marketing spin. The nuts and bolts of this business have changed little. Answer your phone, communicate effectively and work collaboratively. None of this is rocket science. The real differentiation is character and what your agent does when no one is watching. Just like in life.
